Hagane no Alphonse
It's going to be interesting to see how they plan to connect the movie to the series. Now that I have seen the ending, I cannot see exactly how the movie is related to it, but it may end up being a retelling of the story from the TV series. This is what they did with Escaflowne.
It's not gonna be a "retelling" of anything. The end of the series wasn't the end - they still have to reunite Ed and Al! It's a continuation...nothing like Escaflowne or X the Movie.
*squee~!* Oh, and someone named Oguri Shun (小栗 旬) will be playing Heiderich, even though Rie Kugimiya did the voice in the trailer. Apparently they changed it...
